New nuclear sites
In November 2009, the Government has identified ten nuclear sites which could accommodate future reactors
· Bradwell in Essex
· Braystones
· Kirksanton
· Sellafield in Cumbria
· Hartlepool
· Heysham in Lancashire
· Hinkley Point in Somerset
· Oldbury in Gloucestershire
· Sizewell in Suffolk
· Wylfa in North Wales. (However, the Welsh Assembly Government remains opposed to new nuclear plants in Wales despite the approval of Wylfa as a potential site)
Most of these sites already have a station, the only new sites are Braystones and Kirksanton.
